前言综合机械化采煤是煤炭工业采煤技术的发展方向,是煤炭工业现代化的标志。我国从1974年引进综采设备以来,综采技术和水平逐年提高,已自行设计,制造几种成套综采设备。特别是1979年引进了一百套综采设备,已陆续下井投产。据我们对九个矿务局的初步调查,显示出综采具有单产高、效率高、生产掘进率低,直接成本低、安全条件好等优点,深受煤矿工人和干部的欢迎,综采已在这些局矿的煤炭生产中占很重要的地位。综采工作面的产量目前一般已占全矿总产量的一半左右,有的矿高达70％以上,综采工作面每月产量往往是全矿(局)当月生产任务能否完成的关键。
Preface Comprehensive mechanized coal mining is the development direction of coal mining technology, is a symbol of the modernization of the coal industry. Since the introduction of fully mechanized mining equipment in China in 1974, the technology and level of fully mechanized mining have been increasing year by year. Several sets of fully mechanized mining equipment have been designed and manufactured by ourselves. In particular, in 1979 introduced 100 sets of fully mechanized mining equipment, have been put into operation. According to our preliminary survey of nine mining bureau, it shows that fully mechanized mining has the advantages of high yield, high efficiency, low production rate, low direct cost and good safety conditions. It is welcomed by coal miners and cadres. In these Bureau of coal production occupies a very important position. At present, the output of fully mechanized coal mining face currently accounts for about half of the total output of the mine and some ore reaches as high as over 70%. The monthly output of the fully mechanized mining face is often the key to the completion of the production task of the whole mine (bureau) in the current month.
